The Prisma II™ optical network is an advanced transmission system designed to optimize network architectures and increase reliability, scalability, and cost effectiveness. Prisma II 1550 nm Optical Amplifiers offer a wide range ofconfigurations and output powers for the ultimate in network architecture flexibility.

The Prisma II Optical Amplifiers are available as single modules with various output options or as configured amplifier systems with a pre-amplifier and a corresponding amplifier module. Additional post-amplifier modules can bedesigned in for greater routing capabilities.

Gain Flattened EDFAThe Prisma II Gain Flattened Erbium Doped Fiber Amplifier (EDFA) is designed for use in multiple wavelength systems. This highly versatile EDFA maximizes system performance and flexibility by providing automatic gain control (AGC) while maintaining gain flatness for up to 40 wavelengths. The Prisma II Gain Flattened EDFA gives the user the flexibility to select between having constant composite output power or having constant gain per wavelength.

Configurable Optical Amplifier SystemThe configurable system consists of one high-power 8 x +17 dBm pre-amplifier module and one post-amplifier module. The post-amplifier module is available with various number of output port and power output options. For flexibility in network expansion, add-on post-amplifier modules can be added to the configurable system.

Add-On Post-Amplifier ModulesUp to seven (7) additional post-amplifier modules can be used with the configurable system for outstanding network expansion capabilities. Post-amplifier modules require the high optical input provided by the pre-amplifier modules of theconfigurable system.

The Prisma II™ optical network is an advanced transmission system designed to optimize network architectures and increase reliability, scalability, and cost- effectiveness. Prisma II 1550 nm Transmitters offer the ultimate in networkarchitecture flexibility with products designed specifically for broadcast or narrowcast transmission at long or extended distances.

The Prisma II™ optical network is an advanced transmission system designed to optimize network architecture and increase reliability, scalability, and cost effectiveness. The 1310 nm High Density Transmitters (HDTx) are designed for use in the standard Prisma II chassis* and utilize standard power supplies and fan tray. The ability to mix high-density transmitter modules with other PII modules in the same chassis greatly enhances the flexibility of the platform. Up to 26 transmitters can operate in a standard 6 RU Prisma II Chassis effectively doubling the density for 1310 nm transmitters in the chassis. The transmitter has 1 GHz passband which greatly increases the bandwidth for high definition TV and other advanced services. Microprocessor control allows ease of installation and flexibility of application. The transmitters are offered in a wide range of output powers, from 3 dBm to 15 dBm.

The Laser Link® Modular 1310 nm Optical Transmitters are part of an advanced transmission system designed to optimize network architectures and increase reliability, scalability, and cost effectiveness. The Laser Link III 1310 nm transmitters are designed to operate over a wide range of optical output powers and loss budgets, delivering both analog and digital signals.

The LLT III series of transmitters are half-width modules. Up to 14 modular LLT III transmitters can be housed in the Laser Link Mainframe or 4 modules in the Laser Link Mini-mainframe offering compact installation, improved system reliability and a telemetry interface for Network Management (status monitoring).

The Laser Link® Modular 1550 nm Optical Transmitters are part of an advanced transmission system designed to optimize network architectures and increase reliability, scalability, and cost effectiveness.

The Laser Link 1550 nm Transmitter Family includes the Externally Modulated Transmitter (LEMT), Narrowcast Transmitter (LLNT), and Narrowcast Return Transmitter (LLNTR). These 1550 nm transmitters are designed to operate over a wide range of optical output powers and loss budgets, delivering both analog and digital signals.

The 1550 nm LEMT applications include supertrunking, hub interconnects, broadcast transmission portion of DWDM architecture and 1310/1550 nm overlays. The LLNT converts input RF narrowcast signal in the 50-870 MHz frequency range to an optical output with a discrete ITU grid wavelength. LEMT Transmitter Multiple outputs of LLNT products (20 currently) may then be transmitted over a single fiber through utilization of wave division multiplexing. The LLNTR converts RF signal inputs in the 5-210 MHz frequency range to an optical output with a discrete ITU grid wavelength. LLNTR outputs of differing wavelengths may then be combined for amplification and transport over a DWDM system.

The Laser Link® Forward Receiver (LLFR) receives optical signals, then converts them to RF and transmits them into the network. Up to 7 modular forward path receivers can be housed in the Laser Link Mainframe, or 2 modules in the Laser Link Mini-Mainframe, offering compact installation, improved system reliability and a telemetry interface for Network Management (status monitoring).

The ELLRR-S Reverse Receiver (ELLRR-S) receives analog or data upstream signals from a node or a hub location. Up to 14 modular return receivers can be housed in the Laser Link Mainframe or 4 modules in the Laser Link Mini-mainframe, offering compact installation, improved system reliability and a telemetry interface for Network Management (status monitoring).
